Be it known that I, CHARLES GoozEY, a citizen of the United States, and resldent of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Spring-Rings, of which the following is a specification.

This invention relates to spring rings of the class used as a connector for chains for personal wear, and has for its object to provide a ring of improved construction which is formed of sheet-metal and in two halves, each half being struck up into concavo-convex form in cross section and means being provided for connecting said halves together.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation of my improved spring ring.

Fig. 2 is a side elevation of my improved ring showing one of the halves of the body portion removed.

Fig. 3 is a side elevation showing one of the halves of the ring as it appears when struck up from sheet stock.

Fig. 4 is an enlarged cross section on line 4.-4 of Fig. 1 showing the overlapping construction on the inner side of the ring whereby two halves are connected together.

Fig. 5 is a section showing the overlapping construction on the outer side of the ring.

Fig. 6- is a section showing the overlapping construction on both the inner and outer sides of the ring.

Fig. 7- is a sectional view similar to Fig. 1 but showing the inner edges of the halves rolled over each other and clenched.

Referring to the drawings, 10 designates one of the halves of the ring and 11 the opposite half thereof both being formed from sheet stock and blanked out primarily into the shape illustrated in Fig. 3, the inner edge 12 of both halves of the ring being swaged out thin as illustrated at 12 in Fig. 4. while the outer edge 13 may be left the normal thickness of the stock. In blanking out these halves the recess 14 is formed on the outer periphery whereby when the I s ec es-ea of Letters Patent.

halves arebent up into: concavosconvex shape these notches provide between them an elongated opening15, see Fig.2, through which the operating handle 18 of the slide bar 19 projects.

In some cases I also provide inwardly and outwardly extending radial lugs 16 which when the parts are attached together may be bent inwardly as illustrated in Fig. 2, to

form an abutment for the operating spring 17.

In assembling the parts of my improved spring ring, after the halves have been struck up into the concavo-oonvex shape, a portion of these halves is cut out as at 20, forming an opening into the ring; the slide bar 19 and spring 17 are then positioned in the half 10 and the half 11 is placed over the half 10 and its thin edge 12' is rolled, bent or burnished over the corresponding edge of the opposite half, thereby firmly securing the two halves together.

I do not limit myself to the rolling or bending of the inner edge of one half over that of the other, as the outer edge of one half may be rolled over that of the other, as illustrated in Fig. 5, if desired or in other cases, both the inner and outer edges of the halves may be rolled over each other.

In some cases it may be desired to connect and lock the halves by rolling, turning or clenching their edges together in a manner similar to that illustrated at 21 in Fig. 7.

My improved construction of ring has a number of important advantages; first, it may be made in halves struck up from sheet stock and as thin as desired: second, these halves are connected together by rolling, turning 0r bending the edge of one half over that of the other: third, the whole ring is constructed without the use of solder, which is of great importance in the manufacture of this class of jewelry: fourth, the cost of production is greatly reduced over rings formed of the usual tubing.

Having thus described one illustrative embodiment of my invention I desire it to be understood that the details of construc 'tion may be varied without departing from the spirit of my invention, thescope of the sponding surface of the other half to secure the tWo parts together.
